For its size, Dayton, Ohio was once one of the most productive and creative cities in the U.S. It produced more patents per capita at the turn of the century than any other. The city was home to several former great Fortune 500 companies, including National Cash Register, Mead Paper and Phillips Manufacturing. Through the first half of the 20th century, Dayton had one of the healthiest manufacturing industries. It had more GM autoworkers than any city outside of Michigan during World War II. In the past 50 years, Mead has merged with West Virginia Paper and moved to Richmond, and GM has closed one plant after another in the city.
